Title: Temp. detector for liq. baths - comprises two tubes held in rest position against spring by bimetallic hook deforming at detection temp
IPC: G01K5/70
Filed: 1975-08-08
Abstract: The temperature detector produces a signal when the temperature of a liquid bath has reached a preset value two elements (1, 4) can move w.r.t. each other between a "release" position corresponding to the signal and a "locked" position. They are brought towards the "release" position by an elastic system (7) and maintained in the "locked" position, against the action of the elastic system, by the locking of an elastic hook on a bolt-type system (5). The hook comprises a bimetallic strip whose characteristics and positioning are s.t. at normal temperatures, its free end can engage in the bolt system. At the detection temperature, its deformation is sufficient for its to escape from the bolt.

Title: Fuel regulator for gas turbine propulsion - has hot wire anemometer to give flow dependent signal
IPC: F02C9/28
Filed: 1975-10-24
Abstract: The fluid oscillator (13) gives a first input signal (15) to a summing amplifier (16) corresponding to the fuel volume being pumped to the gas turbine mixing chamber. The second signal (21) represents the fuel volume passing to a variable metering valve (14) in series with the fluid oscillator. The output from the amplifier leads to a fuel consumption display unit (28) and a regulator switch (23) which also receives signals from the manual selector (25) giving the desired performance requirements. The metering valve (14) is locked hydraulically when no correction signals are received. The fluid oscillator has a fuel inlet union which branches into two channels one of which contains an anemoneter with a heater element whose temperature is dependent upon the fluid volume passed.

Title: Propellant powders based on cellulose nitrate - contain potassium ortho phthalate, stearate or sorbate as antiflash agent
Inventor: LENEVEU LOUIS
IPC: C06B23/04
Filed: 1975-12-17
Abstract: Propellant powders based on nitrocellulose (NC) and opt. other propellants, contain potassium o-phthalate (I), potassium stearate (II) or potassium sorbate (III) as antiflash agent, used e.g. at =1% on propellant. The named potassium salts replace crystalline mineral salts such as K2SO4 previously used in propellants to prevent re-ignition of the combustion gases in the muzzle of the gun. Compared with known additives, the (I), (II) or (III) do not affect the gelation of the nitrocellulose with palsticisers such as dibutyl phthalate, dioctyl phthalate, etc, do not reduce the chemical stability or temp. coefficient of the propellant, and do not leach out during 'with solvent' processing during immersion in water.
Patent FR-2288075-A1 (FR)
IPC: C07D317/26
Filed: 1976-01-19
Abstract: To prepare the liquid acetals having a solubility of less than 10% by weight in 25 DEG C water, monoalcohols and/or diols having at least 4 carbon atoms and, in the case of diols, having not more than 3 carbon atoms between the diolhydroxyl groups are reacted with at least a stoichiometrically equivalent amount of aldehydes and/or dialdehydes. The reaction temperature is between 0 and 100 DEG C; the reaction is carried out in the presence of an acidic catalyst. The product obtained is a two-phase, aqueous-organic liquid in which the acetals are present in the organic phase. Advantageously one equivalent of alcohol is reacted with 1 to 1.5 equivalents of aldehyde. The novel process is used for example for preparing acetals having 6-membered rings, i.e. 1,3-dioxanes from 1,3-diols and aldehydes, especially for reacting acrolein with 2-methyl-1,3-propanediol to form 2-vinyl-5-methyl-1,3-dioxane as per the reaction scheme Product acetals with an olefinic double bond can be converted into corresponding acetal aldehydes by hydroformylation. The novel method of preparation makes it possible to obtain the acetals in a yield which is higher than that corresponding to the thermodynamic equilibrium.

Title: Attachment of tubular rails to supports - using clamp bolts inserted through slots in rails and formed with locating plates welded in place
IPC: F16B37/04
Filed: 1976-02-24
Abstract: A longitudinal slot (5) is cut in the centre of one face of the tube (2) and a similar, shorter, vertical slot in the support (3). A threaded shank (6) carries a plate (7) which is slightly shorter and narrower than the longitudinal slot dimensions, so that it can be inserted in the slot and rotated through 90 deg. to retain it in position. The projecting shank is then inserted in the hole in the support and secured by a nut (10) and washer. The plate (7) is attached to the end of the shank by welding (9). Rotation of the assembly during tightening is prevented by providing flats (12) on the shank end or a raised portion (13) at the centre of the plate to locate in the width of the longitudinal slot.

Title: Charging circuit for battery - has DC=DC converter comprising chopper of variable frequency or conduction period
Inventor: LECLUSE JEAN-FRANCOIS
IPC: H02J7/02
Filed: 1977-05-13
Abstract: The charging circuit, for a battery, has a dc/dc converter containing a multistage chopper breaking the supply dc voltage into an ac signal whose frequency may be varied by controlling the stages in the chopper. Each chopper stage consists of and on/off transistor. Varying the chopping frequency alters the dc charging voltage/current. Alternatively, the charging voltage/current may be altered by altering the time for which the chopper's transistors are conducting. The advantage lies in simplicity. The multi-stage system is mutually out of phase at a angle equal to 2T1/n where n is the number of choppers.
